Title: Frequency changing apparatus for inter-communicating radio telephone systems
IPC: H04B1/50
Filed: 1943-08-10
Abstract: 569,637. Wireless signalling. MURDOCH & CO., Ltd., J. G., and HENDERSON, B. J. Aug. 10, 1943, No. 12925. [Classes 40 (iii) and 40 (v)] A frequency changing device for radio-telephone apparatus employing an elongated U-shaped member as part of a tuned circuit, a hand micro-telephone and a support for the latter, comprises arms for the U-shaped member of changeable length between set limits and an electro - magnetic device whose circuit is closed by a contact operated on lifting the hand piece from its support for changing from one of said lengths to another. Fig. 1 shows the arrangement at any one of the stations in a system in which a station making a call transmits on a frequency y and receives on a frequency x. E is the telephone hand-set, F the transmitter and G the receiver. In the rest position, the transmitter F is set to a frequency x and the receiver C to a frequency y so as to be ready to receive a call employing a transmitting frequency y and a receiving frequency x. Thus to make a call it is necessary to change the frequency of transmitter F to y and the frequency of receiver G to x. This is done by lifting hand-set E to close contact C which energises relay P/2, contacts P2 of which energise in parallel a solenoid S for changing the transmitter frequency, and relay T/1 which changes the receiver frequency. When a call is received however contact Q2 is opened by relay Q /2 thus preventing a change of frequency on lifting the hand-set. The apparatus is adapted for operation at very high frequencies and the transmitter frequency is determined by means of a U-shaped conductor assembly comprising tubes a, sliders b and a connecting bridge d. The free ends of the tubes, not shown, are connected to the anodes of a pair of push-pull valves. The two frequencies are obtained by moving bridge d to two positions by means of a member f operated by solenoid S. The receiver frequency is determined by a similar resonant pair j terminated by an adjustable bridge k and connected in circuit with the local oscillator. A loop m coupled to the pair j is short-circuited by contact Tl of relay T/1 to change the frequency. Where each station has its own receiving frequency, the transmitters must be provided with a number of solenoids S acting independently on the tuning means to select the frequency of the desired called station.

Title: Methods and apparatus for measuring the speed of propagation of electromagnetic waves in the ground
Inventor: GABILLARD ROBERT
IPC: G01V3/12
Filed: 1966-03-24
Abstract: 1,143,965. Measuring velocity of radio waves. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 24 March, 1966 [24 March. 1965], No. 13080/66. Heading H4D. In a method of measuring the velocity V of electromagnetic waves in the ground of frequencies suitable for use in geophysical prospecting each of two spaced stations emit in the ground within regularly spaced intervals of time a pulse of the waves, detects the wave emanating from the other station, and applies during emission an attenuation to received waves to prevent utilization on the latter during emission; the frequency at one of the stations is adjusted until a constant time difference is obtained at each station between emission and reception; the constant time difference is measured for each station; and the duration for the two-way travel of the waves is derived from the measures. The invention also comprises analogous apparatus, Fig. 2 (not shown). The ground will generally be dispersive and the variation over the path of interest of velocity V with frequency F may be measured. One of the stations may be moved to afford a " map " of values of V over an area, the anomalies in V enabling detection of the nature and structure of the subterranean formations. In on embodiment each station includes a cathode-ray oscilloscope showing on an upper horizontal time-base the counterpart of the transmitted pulse and on the lower horizontal time-base the pulse received from the other station, Fig. 2c (not shown): if the time interval between the peaks of the two pulses at one station is T A  and at the other station is T B  it is shown that V = (distance between the stations).2/T A + T B ) when the frequency at one station is adjusted for stationary displays. The radio link between the stations may be utilized for telephone communication. One station may be on the surface with the other station in a mine gallery, Fig. la (not shown), or each station may be in a tunnel, Fig. 1b (not shown).
